Chronic phencyclidine abuse and physical assault

A M Khajawall, T B Erickson, G M Simpson

    The American Journal of Psychiatry
    |December 1, 1982
    PubMed
    Summary

    Aggressive behavior did not differ between phencyclidine (PCP) and heroin units. However, higher urinary PCP levels were found in patients admitted for aggression compared to those with violent behavior, suggesting complex PCP-behavior links.

    Area of Science:

    • Psychiatry
    • Toxicology
    • Behavioral Science

    Background:

    • Phencyclidine (PCP) is a dissociative drug associated with aggression.
    • Understanding the relationship between PCP levels and aggressive behavior is crucial for effective treatment.

    Purpose of the Study:

    • To investigate aggressive behavior in patients undergoing phencyclidine (PCP) detoxification.
    • To compare aggressive behaviors on PCP and heroin detoxification units.
    • To examine the correlation between urinary PCP levels and aggressive behavior.

    Main Methods:

    • Comparative analysis of aggressive behaviors on PCP and heroin detoxification/rehabilitation units.
    • Measurement of urinary PCP levels in patients admitted to a PCP unit and an acute psychiatric ward for violent behavior.
    • Statistical comparison of PCP levels between patient subgroups.

    Main Results:

    • No significant differences in aggressive behavior were observed between the phencyclidine (PCP) and heroin units.
    • Patients admitted to the PCP unit with PCP-positive urine exhibited significantly higher urinary PCP levels compared to violent patients with PCP-positive urine admitted to an acute psychiatric ward.
    • A subgroup analysis of 75 patients on the PCP unit and 75 patients on the acute psychiatric ward was conducted.

    Conclusions:

    • Aggressive behavior patterns may not differ solely based on the primary substance (PCP vs. heroin) in detoxification settings.
    • Higher urinary PCP levels correlate with aggression in specific patient populations, but the direct link to behavior requires further investigation.
    • Further research is needed to clarify the relationship between PCP concentrations in biological samples and observed behavioral outcomes.
